Abstract

A digital stethoscope includes a stethoscope housing defining a housing edge. The digital stethoscope also includes a surface region secured to the stethoscope housing at the housing edge, and a number of microphones. The digital stethoscope also includes a processing device disposed within the stethoscope housing and in communication with the microphones. The processing device receives the digital audio data from the microphones.

Claims (48)

1. A system, comprising:

a digital stethoscope comprising:

a stethoscope housing; and

a plurality of microphones secured to a surface region of the stethoscope housing, wherein the stethoscope housing defines a circular housing edge; and

a mobile computing device communicatively coupled to the digital stethoscope, the mobile computing device to:

receive digital audio data from the plurality of microphones;

analyze the digital audio data to determine a location of the digital stethoscope;

determine an optimal location of the digital stethoscope;

if the digital stethoscope is not in the optimal location, generate instructions for moving the digital stethoscope toward the optimal location; and

display the instructions for moving the digital stethoscope toward the optimal location.

2. The system of claim 1 , wherein the mobile computing device is further to:

analyze the digital audio data to generate audio classification data associated with the digital audio data; and

classify, based on the audio classification data, the digital audio data as being received from an audio source.

3. The system of claim 2 , wherein the audio source comprises one of a heart, a lung, a joint, an abdomen or other body part.

4. The system of claim 2 , wherein the mobile computing device determines the location of the digital stethoscope with respect to the audio source and determines the optimal location of the digital stethoscope with respect to the audio source.

5. The system of claim 2 , wherein the mobile computing device is further to:

generate a database including the digital audio data and the audio classification data.

6. The system of claim 2 , wherein the mobile computing device displays a visual representation of the location of the stethoscope housing with respect to the audio source.

7. The system of claim 1 , wherein the mobile computing device displays graphical images representing the digital audio data.

8. The system of claim 1 , wherein the mobile computing device is further to:

classify the digital audio data as indicative of an abnormality; and

transmit the classification to the portable electronic device.

9. The system of claim 8 , wherein the mobile computing device displays the classification.

10. The system of claim 2 , wherein the mobile computing device uses an artificial intelligence (AI) engine to classify the digital audio data as being received from an audio source.

11. A method comprising:

receiving audio signals by a plurality of microphones of a digital stethoscope, the plurality of microphones secured to a surface region of a stethoscope housing of the digital stethoscope, the stethoscope housing defining a circular housing edge;

transmitting, by the plurality of microphones, digital audio data representing the audio signals to a mobile computing device;

analyzing, by the mobile computing device, the digital audio data to determine a location of the digital stethoscope;

determining an optimal location of the digital stethoscope;

if the digital stethoscope is not in the optimal location, generating instructions for moving the digital stethoscope toward the optimal location; and

displaying, on a display of the portable electronic device, the instructions for moving the digital stethoscope toward the optimal location.

12. The method of claim 11 , further comprising:

analyzing the digital audio data to generate audio classification data associated with the digital audio data; and

classifying, based on the audio classification data, the digital audio data as being received from an audio source.

13. The method of claim 12 , wherein the audio source comprises one of a heart, a lung, a joint, an abdomen or other body part.

14. The method of claim 12 , wherein the location of the digital stethoscope is determined with respect to the audio source and the optimal location of the digital stethoscope is determined with respect to the audio source.

15. The method of claim 12 , further comprising:

generating a database including the digital audio data and the audio classification data.

16. The method of claim 12 , further comprising:

displaying, on the display of the mobile computing device, a visual representation of the location of the digital stethoscope with respect to the audio source.

17. The method of claim 11 , further comprising:

displaying, on the display of the portable electronic device, graphical images representing the digital audio data.

18. The method of claim 11 , further comprising:

classifying the digital audio data as indicative of an abnormality; and

transmitting the classification to the portable electronic device.

19. The method of claim 18 , further comprising:

displaying the classification on the portable electronic device.

20. The method of claim 12 , wherein the digital audio data is classified as being received from an audio source using an artificial intelligence (AI) engine.
